Why not? Hardly unheard of for managing infrastructure. If we were talking about desktop environments, then maybe, and to be fair, I never said I was a casual user, just that I didn't find prometheus particularly difficult to manage in a production environment.
The implication is that by virtue of using NixOS, you're already a self selected power user. The people that would find setting this thing up in production difficult and the people who would use NixOS are a very small overlap, if any, on that venn diagram.
NixOS is an additional thing on top of prometheus, not a replacement. Not sure why it'd dictate how easy/hard it is to run prometheus & co, you still have to know the same stuff as without it.
You miss the point I’m making which is that if you’re smart enough to use NixOS, you are not representative of gen pop at all. so you saying something is easy doesn’t really say much about the struggles gen pop has with these kinds of things.
In other words, I would absolutely expect a NixOS user to understand how to stand up prom in prod. But I wouldn’t value a statement from that person saying that it’s easy to do so because of course it is. You use NixOS. You might argue that the skill sets are entirely different, and I might accept that argument, but then still say, if you are smart enough and masochistic enough to beat your head against the wall to use NixOS, then deploying prom in prod is obviously going to be trivial to you.
